TECHNICAL FIELD

The present disclosure relates to the technical field of communicationapplications, and in particular to a communication method, a mobileterminal, a base station, and a computer readable storage medium.

BACKGROUND

In the future, some operators will deploy 5G new radio (NR) on the Ccarrier (around 3.5 GHz). However, uplink and downlink budgets at 3.5GHz have a large difference (a loss of downlink transmission is about 10dB lower than a loss of an uplink transmission), which causes that anuplink coverage is significantly smaller than a downlink coverage.

The main reason for the large difference between the uplink and downlinkbudgets is that an uplink transmit power of a mobile terminal is muchlower than a downlink transmit power of a base station, a downlinkantenna is configured with 64 transmitters and 4 receivers, and anuplink antenna is configured with 1 transmitters and 64 receivers, whichcauses that the uplink coverage is significantly smaller than thedownlink coverage. The difference between the uplink and downlinkbudgets causes a coverage of 5G network to be limited to the uplinkcoverage, and the uplink coverage of 3.5 GHz is 5 dB worse than anuplink coverage of 4G network of 2.6 GHz of China Mobile (a gap mainlyat a propagation loss), which causes that the 5G base station cannotachieve continuous coverage when sharing a station address with a 4Gbase station, thereby adversely affecting usage experience of 5G users.

In order to solve the above-mentioned problem that the uplink anddownlink budgets of 5G have a large difference, and to support Long TermEvolution (LTE) to be gradually upgraded to NR in a frequency domain,the 3GPP Rel-15 NR WI (work item) includes research contents ofco-existence of uplink spectrums of LTE and NR. However, there is norelevant solution in the uplink spectrum co-existence technology for howto perform cell camping, access, and/or uplink transmission.

DETAILED DESCRIPTION

Technical solutions in embodiments of the present disclosure are clearlyand completely described below with reference to accompanying drawingsin the embodiments of the present disclosure. It is obvious that thedescribed embodiments are only a part of the embodiments of the presentdisclosure, and not all of the embodiments of the present disclosure.All other embodiments obtained by a person of ordinary skill in the artwithout creative effort based on the embodiments of the presentdisclosure shall fall within the protection scope of the presentdisclosure.

As shown in FIG. 1 , some embodiments of the present disclosure providea communication method, which is applied to a mobile terminal, andincludes steps 101 and 102.

Step 101 includes: obtaining a target resource for an uplinkcommunication in a current communication process, where a frequencypoint corresponding to the target resource includes a first servingfrequency point of a non-new radio NR communication system, and acommunication system where the mobile terminal is located is a new radioNR communication system.

The first serving frequency point specifically includes 1.8 GHz, 800MHz, 900 MHz, 2.3 GHz, 2.6 GHz, or 2.1 GHz. An example of 1.8 GHz isgiven in the following, and the other frequency points are similar. Thesecond serving frequency point is specifically a 5G NR deploymentfrequency point, including 3.5 GHz or other frequency points, 3.5 GHz isgiven as an example below, and the other frequency points are similar.

The non-new radio NR communication system in this specification may bespecifically an LTE communication system, and the current communicationprocess specifically includes processes of cell camping, random accessor data transmission. Since the communication system where the mobileterminal is located is a new radio NR communication system, the mobileterminal can perform uplink transmission or downlink transmissionthrough a second serving frequency point (such as 3.5 GHz) of the NRcommunication system. The frequency point corresponding to the targetresource includes the first serving frequency point of the LTEcommunication system (such as 1.8 GHz), so that the mobile terminal canalso perform uplink transmission through the first serving frequencypoint. That is, the LTE system and the NR communication system share thefirst serving frequency point, and thereby solving a problem in the 5GNR system that an uplink coverage is significantly smaller than thedownlink coverage.

The frequency point mentioned above is a common frequency point in theindustry. The specific frequency point information is as following:

for time division duplex TDD systems:

1.8 GHz: 1880 MHz-1900 MHz (bands: 39);

2.3 GHz: 2320 MHz-2370 MHz, or 2300 MHz-2320 MHz, or 2370 MHz-2390 MHz(bands: 40);

2.5 GHz: 2575 MHz-2635 MHz, or 2555 MHz-2575 MHz, or 2635 MHz-2655 MHz(bands: 41); and

for frequency division duplex FDD systems:

1.8 GHz: 1755 MHz-1785 MHZ, or 1850 MHz-1880 MHz;

2.1 GHz: 1955 MHz-1980 MHz, or 2145 MHz-2170 MHz.

The 800 MHz and 900 MHz frequency points also include any one of 800 MHzand 900 MHz used in CDMA, GSM, and TD-SCDMA systems.

Further, the frequency point corresponding to the target resourcefurther includes a second serving frequency point of the new radio NRcommunication system.

Step 102 includes: communicating with the base station according to thetarget resource.

Specifically, the terminal camps on a cell corresponding to the basestation according to the target resource and performs data transmissionwith the base station, or the terminal accesses to the cellcorresponding to the base station according to the target resource andperforms data transmission with the base station.

The communication method according to the embodiments of the presentdisclosure includes obtaining a target resource for an uplinkcommunication in a current communication process, where a frequencypoint corresponding to the target resource includes a first servingfrequency point of a LTE communication system, a communication systemwhere a mobile terminal is located is a new radio NR communicationsystem, and communicating with a base station according to the targetresource. In the embodiments of the present disclosure, uplinktransmission may be performed by using the first serving frequency pointof the LTE communication system and the second serving frequency pointof the NR communication system, and communication between the terminaland the base station is achieved on the premise of sharing the uplinkfrequency point.

As an optional implementation manner, the above step 101 includessubstep 1011, which includes: obtaining the target resource for theuplink communication in the current communication process based on anagreement of a predefined protocol.

In an embodiment of the present disclosure, an uplink frequency pointused in processes of cell camping, random access, and data transmissionmay be predefined in a protocol.

As another optional implementation manner, the above step 101 includessubstep 1012, which includes: obtaining the target resource for theuplink communication in the current communication process according toresource indication information transmitted by the base station.

The resource indication information herein is transmitted by the basestation by using at least one of: a reference signal, a physicalbroadcast channel, system information, or a dedicated radio resourcecontrol RRC signaling. Alternatively, the resource indicationinformation is transmitted by a newly added reference signal or a newlyadded channel in a synchronization signal block.

The base station broadcasts in a physical broadcast channel PBCH (Mastersystem Information Block, MIB), a synchronization signal block, or asystem information block SIB (a certain SIB message, such as SIB2), orinforms a UE of an uplink transmission frequency through a dedicatedradio resource control RRC signaling, or informs the UE of a frequencyused for random access or a frequency used for camping, for example, 3.5GHz and/or 1.8 GHz, which makes the UE know which frequency point isused to perform random access, uplink transmission, or camping.

The resource indication information transmitted by the base stationenables the terminal to know the frequency point for accessing orcamping earlier.

The above target resource specifically includes a cell or a frequencypoint.

In a case that the above target resource is a cell, the above substep1012 includes substep 10121, which includes: selecting a target cell tocamp on from candidate cells according to a frequency point supported bythe mobile terminal, in a case that the resource indication informationincludes frequency point information corresponding to the candidatecells, and determining the target cell as the target resource.

Specifically, it is determining that a first candidate cell bars themobile terminal from camping on or accessing to the first candidatecell, and selecting the target cell to camp on from the other candidatecells except the first candidate cell, in a case that frequency pointinformation corresponding to the first candidate cell in the candidatecells indicates that the first candidate cell supports the first servingfrequency point for uplink transmission or does not support a secondserving frequency point of the NR communication system for uplinktransmission, and an uplink frequency point supported by the mobileterminal does not include the first serving frequency point.

In an embodiment of the present disclosure, the base station transmitsthe frequency point information corresponding to the candidate cells tothe terminal, so that the terminal can identify earlier whether thecandidate cell is a cell barring the mobile terminal from camping on oraccessing to the cell, so as to avoid the mobile terminal delayinginitiating a service.

In a case that the above target resource is a cell, the above substep1012 further includes: correcting a determination parameter used inperforming cell reselection or cell selection for each of the candidatecells based on a preset offset parameter, in a case that the resourceindication information includes the frequency point informationcorresponding to the candidate cells, where the determination parameteris calculated according to an S criterion or an R criterion for cellselection; and determining the target cell according to the correcteddetermination parameter.

A step of correcting the determination parameter used in performing cellreselection or cell selection for each of the candidate cells based onthe preset offset parameter includes:

adding the preset offset parameter to the determination parameter, in acase that the uplink frequency point supported by the mobile terminalincludes the first serving frequency point, and the frequency pointinformation corresponding to one of the candidate cells indicates thatthe one candidate cell supports the first serving frequency point to beused for uplink transmission or does not support the second servingfrequency point of the NR communication system to be used for uplinktransmission; or

subtracting the preset offset parameter from the determinationparameter, in a case that the uplink frequency point supported by themobile terminal does not include the first serving frequency point, orthe frequency point information corresponding to one of the candidatecells indicates that the one candidate cell does not support the firstserving frequency point to be used for uplink transmission or supportsthe second serving frequency point of the NR communication system to beused for uplink transmission.

The mobile terminal can camp on a cell matching the supported frequencypoint and the capability of the mobile terminal with a relatively highprobability, by correcting the above-mentioned determination parameter.

In a case that the above target resource is a cell, the above substep1012 further includes: setting camping priorities for the candidatecells according to the frequency point supported by the mobile terminaland the frequency point information corresponding to the candidatecells; and selecting the target cell to camp on from the candidate cellsaccording to the respective camping priorities of the candidate cells.

Herein, according to the S criterion or the R criterion applied to thecell selection, the cell selection is performed on the candidate cellshaving the respective camping priorities to obtain the target cell tocamp on.

A step of setting the camping priorities for the candidate cellsaccording to the frequency point supported by the mobile terminal andthe frequency point information corresponding to the candidate cellsincludes:

increasing a camping priority of each of the candidate cells, in a casethat an uplink frequency point supported by the mobile terminal includesthe first serving frequency point, and the frequency point informationcorresponding to the each candidate cell indicates that the eachcandidate cell supports the first serving frequency point for uplinktransmission or does not support a second serving frequency point of theNR communication system for uplink transmission; or

decreasing the camping priority of each of the candidate cells, in acase that an uplink frequency point supported by the mobile terminaldoes not include the first serving frequency point, and the frequencypoint information corresponding to the each candidate cell indicatesthat the each candidate cell supports the first serving frequency pointfor uplink transmission or does not support a second serving frequencypoint of the NR communication system for uplink transmission.

Herein, the camping priorities of the candidate cells are adjusted sothat the mobile terminal can camp on a cell matching the supportedfrequency point and the capability of the mobile terminal with arelatively high probability.

In a case that the above target resource is a cell, the above substep1012 includes substep 10122, which includes: determining an availableuplink frequency point as the target resource, in a case that theresource indication information includes the available uplink frequencypoint, where the available uplink frequency point is configured by thebase station according to capability information reported by the mobileterminal, and the capability information includes an uplink frequencypoint supported by the mobile terminal.

Further, prior to the above substep 10122, the method further includes:transmitting the capability information of the mobile terminal to thebase station, where the capability information includes the uplinkfrequency point supported by the mobile terminal.

Further, the above capability information further includes: whether themobile terminal supports using the first serving frequency point as theuplink frequency point to perform access or perform uplink datatransmission in a slot corresponding to downlink transmission.

The mobile terminal reports the capability information, so that when theUE performs downlink reception using the second serving frequency point,a network does not configure uplink access or uplink transmissionresources for the UE; when the UE does not use the second servingfrequency point to perform downlink reception, the network may configureuplink access or uplink transmission resources for the UE.

Optionally, the communications method further includes: before themobile terminal transmits the capability information, notifying, by anetwork, the UE of an access mode supported by the network through abroadcast or a dedicated RRC signaling; or notifying, by the network,the UE of an uplink transmission mode supported by the network through abroadcast or a dedicated RRC signaling. The access mode and the uplinktransmission mode herein refer to whether the UE supports using thefirst serving frequency point to perform uplink transmission in a slotwhere downlink reception is performed in the second serving frequencypoint at a same time.

As an optional implementation manner, in the above step 102, thecommunicating with the base station according to the target resourceincludes:

performing camping according to the target resource, or performingaccess and/or uplink transmission according to the target resource aftercamping is performed according to the target resource; or

performing access according to the target resource, or performing uplinktransmission according to the target resource access after access isperformed according to the target resource; or

performing uplink transmission according to the target resource.

As another optional implementation, in the above step 102, thecommunicating with the base station according to the target resourceincludes:

performing camping according to a frequency point for camping, orperforming access and/or uplink transmission according to the frequencypoint for camping after camping is performed according to the frequencypoint for camping, in a case that the target resource includes thefrequency point for camping;

performing access according to a frequency point for access, orperforming uplink transmission according to the frequency point foraccess after access is performed according to the frequency point foraccess, in a case that the target resource includes the frequency pointfor access; and

performing uplink transmission according to a frequency point for uplinktransmission, in a case that the target resource includes the frequencypoint for uplink transmission.

Optionally, the performing camping according to the target resourceincludes:

obtaining a first signal strength threshold corresponding to the firstserving frequency point and a second signal strength thresholdcorresponding to a second serving frequency point, in a case that thetarget resource includes the first serving frequency point and thesecond serving frequency point; and

selecting the first serving frequency point or the second servingfrequency point to camp on, according to the first signal strengththreshold, the second signal strength threshold, and a current referencesignal received power RSRP.

A step of obtaining the first signal strength threshold corresponding tothe first serving frequency point and the second signal strengththreshold corresponding to the second serving frequency point includes:obtaining, through a first notification message broadcasted by the basestation, the first signal strength threshold corresponding to the firstserving frequency point and the second signal strength thresholdcorresponding to the second serving frequency point.

In the embodiments of the present disclosure, when the mobile terminalcan camp on two frequency points, different thresholds for cellselection or cell reselection may be set for different frequency points.When the terminal determines that the current reference signal receivedpower RSRP reaches a threshold corresponding to a certain frequencypoint, the terminal may select a corresponding cell and camp on thecorresponding frequency point.

Optionally, a step of performing access according to the target resourceincludes:

obtaining a third signal strength threshold corresponding to the firstserving frequency point and a fourth signal strength thresholdcorresponding to a second serving frequency point, in a case that thetarget resource includes the first serving frequency point and thesecond serving frequency point; and

selecting the first serving frequency point or the second servingfrequency point to access, according to the third signal strengththreshold, the fourth signal strength threshold, and a current referencesignal received power RSRP.

A step of obtaining the third signal strength threshold corresponding tothe first serving frequency point and the fourth signal strengththreshold corresponding to the second serving frequency point includes:obtaining, through a second notification message broadcasted by the basestation, the third signal strength threshold corresponding to the firstserving frequency point and the fourth signal strength thresholdcorresponding to the second serving frequency point.

In the embodiments of the present disclosure, when the mobile terminalcan access to two frequency points, different random access thresholdscan be set for different frequency points. When the terminal determinesthat the current reference signal received power RSRP reaches athreshold corresponding to a certain frequency point, the terminal mayselect the corresponding frequency point, and perform random access tothe corresponding frequency point.

Further, the above step 102 includes: performing access or uplinktransmission in a slot except a predetermined slot and by using thefirst serving frequency point as an uplink frequency point, where thepredetermined slot is a slot used to perform downlink reception by themobile terminal using a downlink serving frequency point of the NRcommunication system.

Specifically, the above predetermined slot include: a slot in whichdownlink reception is performed in a connected mode and using thedownlink serving frequency point, and a slot in which downlink receptionis performed in an idle mode and using the downlink serving frequencypoint. The slot in which downlink reception is performed in a connectedmode and using the downlink serving frequency point includes: a slot forreceiving downlink control information, a slot for receiving downlinkdata, a slot for receiving a broadcast message, a slot for receiving apaging message, and a slot for receiving reference information. The slotin which downlink reception is performed in an idle mode and using thedownlink serving frequency point includes: a slot for receiving downlinkcontrol information, a slot for receiving a paging message, and a slotfor receiving reference information.

It is assumed that uplink frequencies of a NR system include 3.5 GHz and1.8 GHz that is shared with LTE, and the downlink frequency of the NRsystem is only 3.5 GHz. The coverage of 1.8 GHz is larger than thecoverage of 3.5 GHz. As shown in FIG. 2 , a first area is close to thebase station, and the UE can perform uplink transmission using 1.8 GHzand/or 3.5 GHz; a second area is far from the base station, and the UEcan perform uplink transmission only using 1.8 GHz.

The uplink of the NR system shares 1.8 GHz of the LTE system, and whenthe mobile terminal uses 3.5 GHz to perform downlink reception, it isnot possible to use the 1.8 GHz to perform uplink transmission at thesame time. As shown in FIG. 3 , the mobile terminal can perform uplinktransmission using 1.8 GHz only when 3.5 GHz is not used to performdownlink reception. This scheme allows the UE to have only onetransceiver to perform uplink transmission and downlink transmission ina time-division manner, which not only saves the cost of one duplexer,but also reduces adverse effects of intermodulation interference andsecond harmonic wave.

A specific application of the embodiments of the present disclosure isdescribed below.

The base station broadcasts in a physical broadcast channel PBCH (Mastersystem Information Block, MIB), a synchronization signal block, or asystem information block SIB (a certain SIB message, such as SIB2), orinforms a UE of an uplink transmission frequency through a dedicatedradio resource control RRC signaling, or informs the UE of a frequencyused for random access or a frequency used for camping, for example, 3.5GHz and/or 1.8 GHz, which makes the UE know which frequency point isused to perform random access, uplink transmission, or camping. It isassumed that the first serving frequency point is 1.8 GHz, and thesecond serving frequency point is 3.5 GHz.

(I) A mobile terminal selecting a frequency point to camp on accordingto a broadcasted frequency:

(1) if 3.5 GHz and 1.8 GHz are broadcasted, a UE can camp on 3.5 GHzand/or 1.8 GHz;

(2) if only 1.8 GHz is broadcasted,

UEs all camp on 1.8 GHz, or

each UE camps on 3.5 GHz and/or 1.8 GHz (implicitly supporting that 3.5GHz can be used for camping);

(3) if only 3.5 GHz is broadcasted, the UE camps on 3.5 GHz; or

Optionally, after the UE accesses to a certain frequency point, the UEmay transmit a request of a frequency point used to perform uplinktransmission (for example, according to a UE capability, an RRC messageor a UE assistance reporting message request), and a base station sideconfigures an uplink transmission resource for the UE according to thereceived request from the UE.

Implementations of the uplink transmission (UL transmission) are similarto these of RACH.

(III) Uplink transmission:

(1) if 3.5 GHz and 1.8 GHz are broadcasted, the UE can perform uplinktransmission on 3.5 GHz and/or 1.8 GHz;

(2) if only 1.8 GHz is broadcasted,

UEs all perform uplink transmission on 1.8 GHz uplink; or

each UE performs uplink transmission on 3.5 GHz and/or 1.8 GHz(implicitly supporting that 3.5 GHz can be used to perform uplinktransmission);

(3) if only 3.5 GHz is broadcasted, the UE performs uplink transmissionon 3.5 GHz; or

(4) if 3.5 GHz and 1.8 GHz are not broadcasted, and the UE performsuplink transmission on the 3.5 GHz (implicitly supporting that 3.5 GHzcan be used to perform uplink transmission).

The communication method according to an embodiment of the presentdisclosure may also be independent of a broadcasted frequency point, andin the absence of the broadcast frequency point, a certain frequencypoint defined in a protocol or a default 1.8 GHz is directly used toperform random access or camping, or uplink transmission is performeddirectly in an area where 3.5 GHz and/or 1.8 GHz is located.

The communication method according to the embodiments of the presentdisclosure includes obtaining a target resource for an uplinkcommunication in a current communication process, where a frequencypoint corresponding to the target resource includes a first servingfrequency point of a LTE communication system, a communication systemwhere a mobile terminal is located is a new radio NR communicationsystem, and communicating with a base station according to the targetresource. In the embodiments of the present disclosure, uplinktransmission may be performed by using the first serving frequency pointof the LTE communication system and the second serving frequency pointof the NR communication system, and the terminal communicates with thebase station on the premise of sharing an uplink frequency point.

As shown in FIG. 4 , some embodiment of the present disclosure furtherprovides a communication method, which is applied to a base station, andincludes step 401: transmitting resource indication information to amobile terminal, to enable the mobile terminal to determine a targetresource for an uplink communication in a current communication processaccording to the resource indication information and communicate withthe base station according to the target resource, where a frequencypoint corresponding to the target resource includes a first servingfrequency point of a non-new radio NR communication system, and acommunication system where the mobile terminal is located is a new radioNR communication system.

The communication method according to the embodiments of the presentdisclosure includes transmitting resource indication information to amobile terminal, so that the mobile terminal obtains a target resourcefor an uplink communication in a current communication process, andcommunicates with a base station according to the target resource, wherea frequency point corresponding to the target resource includes a firstserving frequency point of a LTE communication system, and acommunication system where a mobile terminal is located is a new radioNR communication system. In the embodiments of the present disclosure,uplink transmission may be performed by using the first servingfrequency point of the LTE communication system and the second servingfrequency point of the NR communication system, and communicationbetween the terminal and the base station is achieved on the premise ofsharing an uplink frequency point.

Further, the frequency point corresponding to the target resourcefurther includes a second serving frequency point of the new radio NRcommunication system.

Further, the above step 401 includes: transmitting the resourceindication information through at least one of: a reference signal, aphysical broadcast channel, system information, or a dedicated radioresource control RRC signaling.

Further, in the above step 401, a step of transmitting the resourceindication information to the mobile terminal includes: transmitting theresource indication information to the mobile terminal by using a newlyadded reference signal or a newly added channel; or transmitting theresource indication information to the mobile terminal by using areference signal or a channel newly added into a synchronization signalblock.

Further, the above step 401 includes: transmitting frequency pointinformation corresponding to candidate cells as the resource indicationinformation to the mobile terminal.

Further, the above step 401 includes:

obtaining capability information transmitted by the mobile terminal,where the capability information includes a frequency point supported bythe mobile terminal; and

configuring, according to the frequency point supported by the mobileterminal, an available uplink frequency point for the mobile terminal,and transmitting the available uplink frequency point as the resourceindication information to the mobile terminal.

Further, the capability information further includes: whether the mobileterminal supports using the first serving frequency point as the uplinkfrequency point to perform access or perform uplink data transmission ina slot corresponding to downlink transmission.

A step of configuring, according to the capability information, theavailable uplink frequency point for the mobile terminal includes:includes: configuring the first serving frequency point as the availableuplink frequency point in a slot that is not used by the mobile terminalto perform downlink reception on a downlink serving frequency point, ina case that the mobile terminal does not support using the first servingfrequency point as the uplink frequency point to perform access orperform uplink data transmission in the slot corresponding to downlinktransmission.

The mobile terminal reports the capability information, so that when theUE performs downlink reception using the second serving frequency point,the network does not configure uplink access or uplink transmissionresources for the UE; when the UE does not use the second servingfrequency point to perform downlink reception, the network may configureuplink access or uplink transmission resources for the UE.

It is assumed that the uplink of the NR system shares 1.8 GHz of the LTEsystem, and when the mobile terminal uses 3.5 GHz to perform downlinkreception, it is not possible to use the 1.8 GHz to perform uplinktransmission at the same time. As shown in FIG. 3 , the mobile terminalcan perform uplink transmission using 1.8 GHz only when 3.5 GHz is notused to perform downlink reception. Such scheme allows the UE to haveonly one transceiver to perform uplink transmission and downlinktransmission in a time-division manner, which not only saves the cost ofone duplexer, but also reduces adverse effects of intermodulationinterference and second harmonic wave.

As shown in FIG. 5 , some embodiments of the present disclosure furtherprovides a mobile terminal 500, which includes:

an obtaining module 501, configured to obtain a target resource for anuplink communication in a current communication process, where afrequency point corresponding to the target resource includes a firstserving frequency point of a non-new radio NR communication system, anda communication system where the mobile terminal is located is a newradio NR communication system; and

a communication module 502, configured to communicate with a basestation according to the target resource.

In the mobile terminal according to an embodiment of the presentdisclosure, the frequency point corresponding to the target resourcefurther includes a second serving frequency point of the new radio NRcommunication system.
